ExBox or Boom Tubes?

[NAKID]

how baffeled can you get with the boomtubes? From the sound of nakids bike, its way to loud. but army_intels biike sounds pretty sweet. Would be great if we could get some professional sound clips of it!

You have to remember, mine is NOT BAFFLED AT ALL...

I don't know who off hand, but there are a couple manufacturers that offer dual underdeat, or seatside highmount pipes that leave a lot more visibility of the rear wheel.  A friend of mine has an S4R with these dual highmounts, and they look pretty slick.  No big gap between wheel and bike, and no wheel removal issues.

Having said that, I gotta say, having the Arrow Ti system with removable baffles if hella nice (on my 06 S2R1K)

Zards makes the dual-underseat configuration... and they supposedly work quite well with the stock ECU.  The guys at Ducpond seem to like them.  They keep the rear wheel exposed, and the pipes tuck in well so as not to clutter things up.  I'm hoping to ride with someone who has them on an S2R so I can hear them.

Look forward to hearing what the Boom Tube guy tells you about baffling.

My Ex-Box have/had no issues with the fitment.  It takes a little wiggling here and there which, is expected with most exhaust systems (auto exhausts are no different) and I see this as "normal" and "acceptable" and not a design flaw.

3000 miles later, zero problems and I still think that the Ex-Box is the only design that flows with the SS monster's.  IMHO

Side note and for future reference since this questions pops up in my inbox once in awhile. My set up are as follows; Ex-Box, DP-open airbox, 14t front sprocket and dealer reprogrammed stock ecu. 







Short video.  Note; video was taken 50 miles after install, the sound is a bit more louder after a few thousand miles.

My boomtubes should be in sometime next week.  I went with the most restrictive baffling, but Mark (Motocreations) said that the baffles are easily removable/interchangeable so I can go with more restriction or less. +1 on talking to Mark.  He is super knowledgeable and not pushy in the slightest.   I posted on another thread that I am going to try and get a professional videographer friend to film the bike with its current system (no udder and cored cans) both sitting still and driving by and then do the same after the boomtube install.  Hopefully all by next weekend......

Anyone know of a high mount system (like the arrows) that use smaller mufflers ?
I as well have been fighting with trying to find an exhaust system that will both give me the sound I want (loud) but also not cover up the back wheel (which was one of the things that drew me to buy the bike).

Maybe I could buy the high mount arrow system, ditch the mufflers, and find some smaller cans ?
Anyone have a Arrow system they wanna sell me minus the mufflers ?  I would almost perfer to have a system that exits the rear of the bike rather than under the bike (like the boomtubes) as far as noice/headache wise.

You may want to consider using a sound recorder rather than any kind of video camera (unless like you said, its a pro model or something)

Too many people do sound reviews on ebay and such that in no way show true sound differences on the bikes. Sure they sounbd different, but you have no idea how. Some guys at work are into Audis and BMWs and are doing this. I may post a "video" of stock 696 and Termi exhaust, but show pictures of the bike instead while playing a mor accurate sound recording.

Just a thought.

(not my bike) but thats essentially how the production models sound when compared to army_intels. Another thing to note is, if you can close that clutch up for the video cause its way to freaking loud!

My friend is a video professional with a pro camera and pro mic's (he freelances for Discovery and is a documentary film maker).  I am also trying to round up a decibel meter.  That is also why I am going to do before and after with the same equipment, because sound recording is relative to the equipment used in the amateur arena and relative to both equipment and the mix on the pro side.

awesome, im sure that's going to work amazing. Post when its done?

I agree..
It would take 5 min to put the stock cover back on (if you still have it) before you shoot the video.
Would def. help with hearing the exhaust and not the clutch.

I'm still waiting for someone to post dyno number(s) on the testa boom-tub'd bikes

To address a few questions and comments from above. (and via two e-mails to myself this morning to post here)

- ExBox?  I've seen them but wasn't that impressed.  But it appears it does a decent job for the price being a mass produced exhaust system.

- Arrows?  Nice systems.  I like the machined couplings and the quality of welds, springs and attachments.  I've had quite a few on/off bikes and never a problem with them.  There are some beautiful welds on these systems!  I have no problem recommending these to folks if the style suits yourself.

- Nakid's BoomTubes?  Older generation model (not like the current design at all). His current setup has ZERO baffling installed (he removed the baffles) -- it is straight pipes.

- Our baffling and sound clips?  All the baffles are custom made in stainlessse.  I tend to vary them depending upon the owners response on what he is looking for in "sound levels".  They will never be whisper quiet -- but given the number of sheriff/police officers running them on Monsters that I know of -- no compliants.  The sound is definitely different than the traditional Ducati rear mounted "exhaust can" setup.  Problem is that since almost every baffle is slightly different, they never sound exactly the same.  And given most are installed via dealerships or owners -- we don't necessarily get many good quality sound clips provided to us. (or that can be compared)  And the sound exits a difference place than the traditional "exhaust can" location -- thus it can sound louder/quieter depending upon where you are recording the sound level from. (some exhaust vendors point their exhausts upward for a reason, less reverb of sounds waves bouncing across the pavement upon exit)

- Materials we use.  System weight for the S4RS setup is 6.5lbs bare. 7.3 w/baffles. 7.5 w/tips. (system variance is @.2lbs depending mostly on baffle construction itself)  We could have gone almost another pound lighter in terms of weight -- but I went with a heavier wall stainless setup (.059 vs industry standard .45-.049ish wall thickness).  Two reasons being 1) longevity and resistance to denting; 2) smoother sound characteristics.  I can instantly identify the material / resonance difference of four sets of identical built BoomTubes in differing materials: .049 mild steel; .059 mild steel; .049 stainless and .059 stainless.  It's why I ultimately chose what we use for the base system setup now.

- Baffles?  For those who think JC Whitney baffles are the hot setup -- think again.  I used something similiar in design until 18 months ago.  Never again.  We now do a handmade perf'd tube that is TIG welded with a few tricks as required to tune the sound.  We only do them in heavier wall stainless as per the exhaust systems themselves.  You get what you pay for.  They are also removable (riveted) for further tuning as required later or complete removal.

Am I an expert in exhaust systems?  No.  I just know what works in making systems like we build and sell (with a lot of experimentation / testing and research work along the way over the years to get to the current production configuration) -- something very minimal in terms of visual style (our "less is more" design mantra), lightweight (under 8lbs complete or less) and still have acceptable street use sound levels. (although not all of our customers use our baffles setups as they want LOUD LOUD LOUD)  

- Carbonfiber crossover/collector assembly w/tips?  Not at this time but it is something we are looking at for summer 2010 if sales warrant.  (it would be retrofitable as well to existing systems)

[addendum]
- The answer is YES -- I've used my exhaust systems to clean the driveway.  Probably the largest displacement dust blower ever created!

Well I called and spoke with Mark, Great guy and very informative. I noticed he posted before I got a chance. Basically he told me what he posted already. When you will want the exhaust, he will ask what you want. He can customize it to your liking. I asked if he can put baffles in so they are not ridiculously loud and have more back pressure so that I can use fatduc and he can have made whatever I want when it comes to it.

He can baffle it as much or as little as you want. Since the baffles come off easily, once you put them on and are not satisfied with the sound level, you can send them back to him so he can modify them to more of your liking.

After speaking with him and the explanation with what he can and can't do for what I want, I think that sometime in the summer I will order the boom tubes from them.

Again big  to Mark for all the questions he answered and to all the people that replied to my post.

So if I read this right, you are saying depending on the baffleing Mark can get a set of BoomTubes to work with nothing more than the FatDuc ? I believe when I spoke with him I was needing a new ECU to run his pipes..?

[Mduc]

When I asked Mark about Fatduc he said that he ran a PC with his pipes. I am the one assuming that if he puts more baffles, fatduc will run since there is more backpressure as with the Quad system.

When I finish the stuff I am doing with the bike now and I get it back, I think I will give boom tubes a try and see if they will work with just the fatduc. Since I dont want to mess with a PC or any other gizmo, I will take a chance to see if it works on my bike. If it doesn't work, I guess I will try to ebay the boomtubes and go with Quad or Arrows.

BTW I am not looking for any gains in power as I really dont care for more, The bike has plenty for me as it is. I am mainly going for the look and sound.

When I try the boomtubes sometime later in the year I will post and let you know how it went.
